KEY.

SPECIFICATION forming part of Letters Patent No. 447,637, dated March 3, 1891. Application filed November 5, 1890. Serial No. 370,425. (No model.)

T0 to whom it may concern.-

Be it known that I, PAREN ENGLAND, re-

siding at Aspen, in the county of Pitkin and State of Colorado, have invented certain new and useful Improvements in Keys, of which the following is a specification.

My invention is an improvement in that class of door-locking keys whicn are provided with an attachment in the form of a supplemental bit pivoted to the keyshank for the purpose of serving as a guard for the keyhole.

In the drawings, Figure 1 is a sectional View of a portion of a lock with my improved key in position. Fig. 2 is a perspective View of the key, and Fig. 3 is a longitudinal section thereof.

In the accompanying drawings, A indicates thelock, and a a the oppositely-disposed keyholes.

B denotes the key, which is most clearly shown in Figs. 2 and 3 of the drawings, by reference to which it will be seen that the same in general appearance is of the ordinary shape, the body portion or stem being, however, apertured longitudinally from its foot part b to the finger member I). In this longitudinal aperture B is disposed a stem O, the lower end of which extends slightly beyond the foot part b of the key, and is provided with a right-angled locking finger or bit 0, which is of the same thickness as the key-foot proper b and extends out flush with the same, as shown. The upper or outer end of the shank O is formed with a flattened head 0', which seats in the looped portion 1) of the key, and arranged for frictional contact therewith, a suitable spring D being employed for this purpose, such springbeing preferably arranged, as shown in Fig. 2, by placing it between the head 0' and the end I) of the key, such construction not only serving to force the head G into contact, as stated, butalso the locking-finger against the foot of the key.

By reference to Fig. l of the drawings the manner in which my improved keyoperates will be clearly understood.

.It will be seen that when the key is inserted through the key-hole a the locking-finger 0 will enter the hole a and plug same up, and as the key B is turned its foot part will be at an angle to the finger 0, (see dotted lines, Fig. 1,) thereby preventing any possibility of the key being pushed from the lock.

By providing the spring D, as stated, the two parts of which the key is composed will be drawn together, so that the key part proper will at all times retain its position in the lock, notwithstanding the jarring and shaking of the door, it also serving to hold the two parts in a true position when the key is out of the look, so that the key will be in proper condition for insertion into the lock.

The key is simple, cheap, easily made,durable, and makes an absolute lock for the purpose intended.

I am aware that it is not broadly new to make a key with a pivotal locking member which will serve to plug up the outer keyhole. I therefore do not broadly claim such construction; but

What I do claim, and desire to secure by Letters Patent, is-

The combination, with the key proper having the bit 17 and hollow shank B rigidly connected, of the key-hole guard composed of the part c, the shank O, and the fiat head O, as shown and described.
